Flight Testing in CoD

[Viper2000]

I think that the first thing we need to do is to try to find standard day conditions.

There are quite a lot of possibilities available.

One option would be to use a relatively modern standard like the ISO standard atmosphere or the 1976 US standard atmosphere. This would facilitate compatibility with modern data. However, the ISO standard atmosphere is not directly available for free.

Alternatively, we could attempt to use older NACA standards; doing so would lend an historical flavour to our work, but might complicate comparison with more modern sources. A few possible standards may be found by following the links below. This list is not exhaustive.

1926 NACA standard
1930 simplification
1952 NACA/ICAO standard
1976 US Standard Atmosphere

I suggest that we use the 1976 standard for comparison purposes because this allows us to avoid some otherwise potentially nasty conversions (eg changes to Temperature scales over time...).

Obviously the next thing that we need to do is to find some way of measuring the atmosphere properties on a variety of available maps so that we can pick the best one for testing.

Does anybody have any suggestions as to how we might best go about this?
